hi there i just set up my dr120 put up my 8ins rvk but the fan noise
is ok.its the sound blasting through the carbon filter its like a jet?
i have it set up like this..

CARBON -FAN -DUCTING

Would it be better if i was to put ducting between the carbon & fan ?

aswell

thanks in advance..i cant grow with this kind of noise...

yeh mate i had the same problem i put about a ft of ducting in,between fan and filter that stopped it.

If that doesn't solve it, you can pick up a cheap fan speed controller to turn it down a bit for reduced noise.

Varispeed fan controller for a tenner and turn it down a bit until its bearable

Cheap fan controller will make it buzz, better of getting a variac based controller

I always put a little bit of ducting between filter>fan don't know if this helps with noise but i assume it might

hey everyone thanks for the info when i bought the fan. i also bought a variac controller
here it is its got 5 settings i have it on number 1 but i need it at 2 or 3 but its too noisey.
so i will buy more ducting and give it a go cheers Mad

hey mad lab....
you might want to use acoustic ducting,,,used in conjunction with your fan controller it should quiten it down considerably,,,,,
an oversized boxed acoustic exhaust and acoustic ducting would work even better but just adding the acoustic duct should really help ,,,,
a bit harder to work with but 8inch will be fine,,,,,
peace and regards 944s2

hey 944s2 i am skint after buying this 8ins fan 8ins acoustic ducting & clamps and 8ins rhino carbon as i said the fan is good the output end is great its the noise going through the
carbon...i hope a meter of ducting helps with noise

[944s2]

sorry I wasn't aware you already had acoustic ducting,,,,
if after running it through the ducting you still think its too noisey and you cant use the controller on a lower speed you may have to put up with it until your can get a boxed acoustic but hoping it will quieten down once you have run it through the ducting,,,,
best of luck,,,,,,s2

i have it on at number 1 i need it at setting number 3 for my 600watt..guess i will have too try it out and see if i get a knock at the door...
